Note
Judge if the set value changed on the temperature control module, and modify the set value only when it changed.
Do not modify the set value of the parameter entered as the setting parameter via the loader port communication. If changed
it, the value written by the PLC comes to be invalid. To make the value by PLC valid, modify it to a different value from the
present one once.
During 1:N connection, until the module which St. No. is "0" starts a communication with PLC, other modules which St. Nos.
are not "0" are in the standby state.
